Paredit for ruby and javascript.

setup-misc.el
;; Enable paredit for a couple for non lisp modes; tweak

Why does paredit not complete curly braces {}?

@johnbendi I had the same question and ended up binding the following function to { in the ruby-mode-map

(defun paredit-open-curly-smart ()
    (interactive)
    (if (or
         (eq major-mode 'rjsx-mode)
         (eq major-mode 'js-mode)
         (eq major-mode 'js2-mode)
         (eq major-mode 'ruby-mode)
         (eq major-mode 'python-mode)
         (eq major-mode 'lua-mode)
         )
        ;; Just do same as `paredit-open-curly' in some mode.
        (paredit-open-curly)
      ;; Otherwise do something smart operation.
      (paredit-open-curly)
      (indent-according-to-mode)
      (comment-indent-new-line)
      (open-newline-above 1)))
